About

Engineer, freelancer,
AI builder.

For the past four years I have worked as a Senior Software Engineer at Enterprise Minds, building hybrid mobile apps and web platforms that run in production. That work includes a payments-enabled PWA which raised user engagement by 40%, and rendering and state-management optimizations that improved app performance by 75%.

Alongside that role I run an active freelance practice, taking products from concept to production for startups in fintech, Web3 and B2B commerce. I own each engagement end to end, from design handoff through to AWS deployment, across both mobile and web.

A growing share of my work now involves Gen AI: integrating LLMs into existing products, building prompt and retrieval pipelines, and delivering AI features that are production-ready rather than proofs of concept.
